[kde-solaris] Is kde-forte's performance claim a myth?

Here is the file command output on the gcc compiled
versin of kate:
kate: ELF 32-bit MSB executable SPARC32PLUS
Version 1, V8+ Required, UltraSPARC1 Extensions
Required, dynamically linked, stripped
So I am guessing that -mcpu=ultrasparc and -mv8plus
are used to compile it. I am not familar with the
KDE source code as a whole. But I wonder in what
area of KDE will the Forte compiler help to optimize
the run-time performance better than the gcc
compiler? Someone already mentioned khtml here.
I frankly didn't see a noticeable performance
difference when loading up the same HTML pages in
both the Forte version and the gcc version of the
konquer. Could it be that being a window system, KDE
is bound to the I/O bottleneck that a good graphics
card and hard drive will diminish any optimization
advantage the Forte compiler has over the gcc?
